Duo Zhang commented on HBASE-15368:
-----------------------------------
Yes, it will pull new data into older windows. So without writing out multiple
files when compaction it will always be a problem that our HFiles are not split
at the exact point... But writing out multiple files is more suitable for fixed
window since the boundary will not move... Cassandra's DTCS uses min timestamp
to calculate window so I think it is something reasonable? We could try I
think. Abstract a WindowFactory can help us try different window implementation
easily.
And for writing out multiple files, I already have a prototype, I could open a
new issue and upload it.
Thanks.
